Surface treatment for medical gloves

Surface treatment

To facilitate release from the hand former, to prevent gloves adhering to one another, and to ensure the gloves fit smoothly, gloves may be dusted, treated by chlorination, or given a polymer coating.

Dusting makes use of talc, silica, crosslinked starch, etc. Chlorination treatment is carried out by dipping the gloves in chlorine solution. Reaction with chlorine creates a very thin layer of chlorinated rubber on the glove surface, thereby preventing tack. The chlorine solution is generated by directly injecting chlorine gas into water or by reacting hydrochloric acid with sodium hypochlorite.

In either case, to preclude deterioration in anti-ageing properties, the glove surface must be neutralised with dilute alkali solution after reaction and then thoroughly washed. Temperature control in the subsequent drying step is also important since the film readily discolours if the temperature is too high.

A widely practised treatment for polymer coating is to dip the gloves in an acrylic or polyurethane type aqueous dispersion diluted to the requisite concentration.

RF-8848 is a modified acrylic copolymers emulsion, specially used for dipping coating as the inner lining of nitrile gloves.

The outstanding characteristics of this product are super soft, excellent chemical stability, high resistance to dinning.
